JAR CLQSURE.

Applicatien filed February as; 1921. Serial No. 442,140.

To aZZ whom it may concern: I

Be it known that 1, JOHN W. Lurnnn'r, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Jar Closures, of which the following is a specification.

This invention relates to improvements in closures for glass fruit jars or the like and has as one of its objects to provide aSimple' and inexpensive clamping 'means for securing the closureiin place upon the mouth of the jar, and whichclamping means will not require to be secured upon the jar by the use of a tying wire or the like.

Another object of the inventionis to provide,.in combination with a ar provided at the opposite sides of its mouth with trunnions, a novel clamping device for the closure for the month which may be readily and quickly engaged with the trunnions or disengaged-therefrom thus greatly facilitatingthe assembling of the clamping means Another object of the invention is to so form the trunnions and the element of the clamping means which is engaged therewith, as to; insure of the clamping means being held against accidental disengagement from the trunnions and yet not interfere with the separation or disengagement 0f theparts when they are intentionally manipulated for this purpose. 7

Another object of the invention is toso form the trunnions and so construct the clamping device that when the clamping de-' vice is locked'to clamp the closure to the mouth of thejar, the member of the device which is engaged with the trunnion will be urged at its engaged portions inwardly toward the/jar so as to provide for a snug and positive engagement" between the parts.

In the accompanying drawing: v

' Figure 1 is a perspective view illustrating the invention; i

Figure 2 is a side, elevation;

Figure 3 is a detail vertical sectional view through one side of the mouth closure of the jar and the clamping means for the closure;

Figure 4 is a perspective View of the locking hail of the clamping device.

In the drawing, the numeral 1 indicates in general a fruit or similar jar of the ordrinary type provided with the usual neck 2 and mouth 3 which latter is closed by a cap 4 disposed thereon and resting at its periphery upon the usual rubber ring 5 disposed to surround the mouth 3. The closure cap 4: is provided upon its upper side with the usual boss/6 having notch 7 fcrthe engagement of the clamping bail of the dc vice which is to clamp the closure in place upon'the mouth. For'the purposesof the invention, the neck 2 of the jar" is'preferably thickened at diametrically opposite points, as at 8, or it may be formed at such points with more or less well-defined bosses the purpose being to reinforce the neck at these points andfat the same time reinforce the trunnions previously referred to and which are indicated by the numeral 9 and are formed integrally WllilltllG thickened. portions 8. Each of the trunnions 9 is substanti ally of frusto-ronical form and is integral at its minor end with the neck 2 at the respective reinforced portion 8, the outer ends of the trunnions being therefore of greater diameter than the inner ends so that the cir cumferential surface of each trunnion provides in effect an inclinedshoulder 10. In order to further reinforce the neck ofthe jar. a reinforcing bead 11 may be formed upon the outer surface of the neck to extend circumferentially thereof between the reinforeed or thickened portions 8. In the specific embodiment of the invention illustrated in the dra ingQthe thickened portion 8 is of circular form and concentric 'to the axis of the'respective trunnion 9 and as this portion protrudes slightly beyond the outer surface of the neck 2, it will serve to suitably space the'portion of the locking device Whichis engaged with thetrunnions, from the adja centsurface of the neck and thus afford the desired clearance between the parts.

The clamping device embodying the in vention comprises a clamping bail which is indicated in general by the numeral 12 and a locking bail. which is indicated in general by the numeral 13. The bail 12 is preferably formed from wire and comprises a connecting portion 1% designed to eXtend across the upper side of'theclosure cap l and to be engaged in'the notch 7 in the boss 6. This bail further comprises depending end portions 15, having inwardly bent terminals 16 for pivotal engagement with the locking bail 13 as Will now beexplained.

The locking bail 13 is preferably formed from sheet metal and is substantially of aJ-shape and is provided at the ends of its side portions 17 with relatively fiat ears 18 gagement with the trunnions 9, the trunnions engaging through the openings 19, and the walls of the openings having pivotal or turning engagement with the shouldered surfaces of the respective trunnions.

Beneath each car 18 each end of-the locking bail 13 is formed with a downwardly proec'ting ear 20 having an opening 21 in which is pivotally engaged the inwardly bent terminal 16 at the respective side of the clampingbail12. If desired the ears 20 may be slightly deflected'laterally as most clearly shown in Figures 3 and 41 ofthe drawings and with relation to the planes of the respective ears 18, so that the side portions 15 of the clamping bail will be adapted to suitably clear theends of the trunnions 9 as the locking bail is swung about its trunnions in clamping or unclampingthe jar closure. I

From the foregoing description of the invention it will be evident that the clamping device may be readily and quickly assembled with the'jar and disengaged ther from'whenever required-and that after ap plication and after the closure cap alias been placed inposition and'the bail 12 en'- gaged with the cap, the bail 13 is to be swung downwardly about the trunnions 9 as pivots and thus shift the pivot points 16 toone side of the axes ofthe respective trunnions 9 and bringing'the intermediate portion of the locking bail 13 to position resting againsttheupper side of the body of the jar, in which position of the parts the closure cap 4; will be securely locked in place. As the locking bail 13 is swung downwardly to lockingposition, the lower sides of the walls of the openings 19 will be caused to bear upwardly against the under sides of thetrunnions 9 and will ride against the inclined shoulders 10 of the'said trunnions. and thus be influenced to move inwardly until the ears 18 seat snugly and firmly against the outer faces of the thickened portions 8 of the neck of the jar. Thus without materially weakening the trunnions 9 or their union with the neck of the jar,

I provide for an interlocking engagement of the ears 18 of the locking bail with these trunnions so as to provide against accidental disengagement ofthe said ears from the trunnions. In the construction illustrated,

and in practice, the axes of the trunnions 9 will be truly diametrically aligned with relation to the mouth or neck of thejar and therefore the trunnions are located more or less exactly at diametrically opposite points upon the said neck, but should it be found desirable to slightly offset these trunnions this may be done without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is:

1. In combination, a container-having a mouth, a closuretherefor, trunnions upon the container at opposite sides of. the mouth having inclined shoulder. portions, and clamping means for the closure including bail having portions pivotally engaging athe inclined portions ofthe trunnions.

2. In combination, a'containerhaving a mouth, a closure therefor, trunnions :upon the container at opposite sides of the mouth tapered in the direction of'their inner ends, and clamping means for the closure in eluding a bail havingportionspivotally ens gaging the tapered portions of the said trunnions.

3. In combination, a container. having a mouth, a closure therefor, trunnions upon the container at opposite sides of the mouth having their lower circumferential portions inclined upwardly and inwardly inithe. direction of their inner ends, and clamping means for the closure includingJt-beiil having portions pivotally engagingftlie said inclined, circumferential portions of .the trunnions. M

4:. In combination, container, having ,a mouth, a closure therefor, substantially frustoeconical trunnions united at their minor ends to the .outer side ofthetmbuth, and clamping meansfor the :closure including a bail having ears formed with openings and pivotally engaging the said trunnions.

.6. In combination, a container having a mouth, a closure for the mouthytrunnions upon the container at opposite sides of'th'e mouth having substantially conical peripheral surfaces, and clamping means for the closure comprising a locking'bail having openings in its end portions. receiving the trunnions with the walls of the ,openings engaging the said conical peripheral surfaces of thetrunnions, and a clamping Ebail engageable with the closure and having its end portions pivotally connected with the end portions of the lockingbail eccentric to-the openings.
